MAGAZINE FEED FOR, CONE WINDERS Thisinvention relates to supports for bobbins from which yarn is adapted to be unwound and fed through a relatively fixed thread guide to a cone or tube of a winding 6 machine.

In United States Patents Nos. 186,045; 755,393; and 1,465,359, devices are illustrated for holding a group of bobbins having the thread at the bottom of one bobbin connected to the thread at the top of the adjacent bobbin, so that the thread wound on all the bobbins of the group may be unwound without stopping any of them for the purpose of tying the thread of one to the thread of another.

Inthese prior art devices the thread at the bottom of'one bobbin is usually tiedto the thread at the top of the bobbin next to it. This. arrangement works very satisfactorily on heavy yarns such as two, three and four ply; but it has been found that considerable breakage, and consequent delay, results when yarns of finer count, which are naturally weaker in strength, are used thereon. This breakage results mainly from thejerk in the long diagonal stretch of yarn between the bottom of one bobbin and the top of the next when the unwinding operation is transferred from one bobbin to the next.

The object of the present invention is to avoid this breakage by grouping the bobbins on their support so that the top of one bobbin is closely adjacent to the bottom of the next bobbin, thereby shortening the length of the free thread between bobbins and lessening the liability to breakage by the jerk incident to the transfer of the unwinding operation from one bobbin to the next. This arrangement, while highly desirable for use with the finer 40, and weaker threads, is not to be considered as limited to such use, as it can be, and is intended to be used with yarns of any number of plys.

Other objects of the invention will become v apparent as the detailed description thereof proceeds.

In the drawings:

F ig.- 3 is a perspective view of the bobbinsupport shown in Figs. 1 and 2;

Fig. 4 is a perspective view of a modified form-of the bobbin support;

Fig. 5 is a plan view of the modification shownin Fig. AL; and

Fig. 6-is a side elevation of another-modi-. fication of-thebobbin support. I

The-bobbin support 1 comprises-a central supporting member-2 having its upper end a bent to form a hook 3 fitting snugly-over the bobbin rail & of the winder. The upper branch 5 of the hook 3 is provided with a recess 6 adapted to receive freely the end of clamping thumbscrew 7 which is screwthreaded into the branch 8 of a clamping U shaped bar 9 having a lower branch 10 adapted 1to contact with the underside of. bobbin rai 4.

As will be obvious from the drawings, the thumb screw 6 forces the branch 5'hard down on the top of rail 4, anddraws the branch 10 tightly against thebottom of rail l, to clamp thelbobbin supporting member securely to the ra1 In this form the support 1 comprisesa part 11, apertured centrally to slidelover. the screw threaded end 12 of. member 2, and provided with a ball bearing-plate 13 supported by balls 14 on a ball race 15 which is held rotatably on end 12 by means of a nut 16 cooperat ing with a nut 17 in positioning the part 11 ]25nd ballbearing members rotatably on mem- Symmetrically of supporting member 2, the zig-zag bobbin supports 18 and 19 extend upwardly from the part 11' toward thebobbin rail 4. Bobbinesupporting spindles 20, 21, 2-2, 23, 24 and 25 are bolted, or otherwisesecured, at their lower ends to parts of the bobbin supports which are slightly inclined to the horizontal soas to cause the axes of the spindles to meet in a point 26 onthe thread guide or slub 27 which guides the threadsfrom thebobbins rotatably mounted. on the spindles to the cones or tubes 28on the winding-machine as: shown diagrammatically in Fig. 1 and represented generally by the numeral.29.-

As shown in Fig. l the thread extends from the top bobbin 31 which is mounted on spindle 20; and the thread at the bottom of the bobbin 31 is tied onto the thread at the top of bobbin 82 which, in turn, is connected at the bottom thereof with the thread at the top of bobbin The bobbins on spindles 23, 24 and 25 are similarly connected, and the thread thereof may be run continuously from one bobbin after the other through the slub and onto the cone 28.

It will be apparent from Fig. 1 that the thread drawn from any of the bobbins mounted on the supports 18 and 19 that the tension of the thread will cause the bobbin support to oscillate slightly on the ball hearing plate 1.5, and this oscillation eliminates unnecessary strain on the thread as it unwinds from the bobbin.

In Figs. 5 and (3, I have shown a bobbin support 3 1 having four bobbin supporting arms 35, 36, 37 and 38, radiating from a central supporting arm 39 clamped to the rail 1 by clamping mechanism similar to that shown in Fig. 1. Each of the bobbin supporting arms is provided with bobbin spindles arranged in the same manner as the corresponding spindles of the modification shown in Fig. 1; that is, with all the spindles radiating to a common point 40 which may be considered as the point of entry of the thread into the thread guide or slub (not shown in these figures).

The support 31 is mounted to oscillate slightly on ball bearing plates similar to those shown in Fig. 1, and the operation of this modification is substantially the same as that of the form shown in Fig. 1.

In the modification shown in Fig. 6 a zigzag support &1 is shown as detachably clamped to the rail d of the winder by means of a thumb nut 4:2 screwthreaded onto the threaded ends of a bolt i3 extending upwardly t'rom the rail 1.

In this modification a bracket is fixed to the back of the upper part of support 41, and is apertured to slide freely over, and pivot on, a bolt 13. The support 11 is substantially the reverse of the supports shown 11 the other modifications, but its spindles 4.5, l6, and 47 radiate, as before, to a common point 41:8 in order to direct the thread from bobbins mounted on said spindles to the thread guide or slub.

It will be apparent from the drawings that all the forms of the invention may have the bobbins applied thereto away from the winder, and may be quickly connected to the bobbin supporting rail of the winding machine. In all cases the thread at the bottom of one bobbin is connected to the thread at the top of the ext bobbin which, in every case, is supported so that the top of one bobbin is closely as possible adjacent to the bottom of the next one nearer to the slub.

This construction, obviously, eliminates all long strands between one bobbin and the next, and thereby reduces liability to breaking of the strand by jerking transfer of the unwinding operation from one bobbin to the next.

Vfhat I claim is:

l. The method of winding and uniting the yarn on a plurality of bobbins which consists in supporting the bobbins to rotate about coplaner axes which meet in a point and arranging the bobbins with the top end of each bobbin, below the bobbin nearest said point, closely adjacent to the bottom end of the next bob-bin nearer to said point.

2. A winding machine having a thread guide and a supporting rail fixed relatively thereto, a bobbin support rotatably secured to said rail, bobbin supporting spindles fixed on said support and having their axes meeting in a point of said thread guide, the top end oi? each spindle below the spindle nearest said thread guide being closely adjacent to the bottom end of the next spindle nearer to said point.

3. The combination with a winding ma chine having a ti read guide and a supportg rail fixed relatively thereto, of a support bobbin supporting spindles fixed thereon with their axes meeting in a common point, and means for detachably and rotatably COHllGi ing said support to said rail with the said common point coincident with a fixed point ii said thread guide, the top end of each spindle below the spindle nearest the thread guide being closely adjacent to the bottom end of the next spindle nearer to said point.

i. The combination with a winding machine having a relatively fixed substantially horizontal rail and a thread guide, of a support detachably fixed to said rail, bobbin holders radiating from said support and mounted to rotate thereon, a pluralitv of spindles mounted on each holder with their axes radiating to a point in said thread guide, each spindle having its top end adjacent to the bottom end 01? the next spindle between it and said point.

In testimony whereof I afiix my signature.
